The Hoya Pro ND 1000 Filter opens up a world of creative possibilities and is designed to reduce light from entering the lens by up to 10 f/stops, without affecting colour balance. This 10 stop neutral density filter allows you to use slower shutter speeds than would normally be possible. An ND filter is the ideal accessory for keen landscape photographers who want to take their images to the next step and is often used to make the clouds look soft and blurry, or to give waterfalls and seascapes a smooth, ghostly look. All Hoya Pro filters have a low-profile one piece aluminium frame to keep the glass secure and parallel to the sensor, while allowing it to be used with super-wide angle lenses.

Neutral Densitiy filters have four main uses:
1) To enable slow shutter speeds to be used, especially with fast films, to record movement in subjects such as waterfalls, clouds, cars, seas etc.
2) To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background.
3) To decrease the effective ISO of high speed film (ie: above ISO400) and allow it to be used outdoors in blight situations.
4) To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which would normally cause over-exposure.
Hoya's range of PRO-ND Neutral Density filters utilises their new metallic ACCU-ND technology to yield a truly neutral colour balance. The Hoya PRO-ND range is aimed at the still photography and HDSLR video markets. Hoya's meticulous use of optical glass and ACCU-ND coating on both surfaces ensures no colour shift as you move from one density to the next - a common problem with other brands of neutral density filters. In conditions of extreme light intensity, such as sunshine on snowy mountains or on the beach, or when using a camcorder, ND (Neutral Density) filters are recommended as essential.
Neutral Density filters are often ignored by photographers, but they have several uses and offer the possibility to achieve otherwise unachievable results. ND filters appear grey and reduce the amount of light reaching the film, they have no affect on colour balance.
